[Elecraft] P3 Temperature Specs

[David Yarnes]

Hi all,

I recently set up my K3/P3 combination on my workbench in my garage in order 
to do some rig comparisons, etc.  The garage is not insulated, and here in 
the desert it can get pretty chilly at night.  Several nights have been 
slightly below freezing outside, and inside the garage it can get down into 
the mid 30's, or slightly higher.

Anyway, I began noticing, on these colder nights, that my P3 didn't want to 
"wake up" for a while.  It would just show "0" for operating frequency, and 
the display was not effective.  Cycling the P3 on and off didn't seem to 
accomplish anything, at least for a while.  Eventually it would wake up, 
presumably after just a little internal heat was generated.  I'm pretty sure 
this is just a temperature thing, since I never have the problem if 
temperatures are more reasonable.  I looked on the Elecraft website, but 
didn't find any "specs" for operating temperature.  I'm just wondering if 
these were ever evaluated.  The K3 doesn't seem to have a problem--just the 
P3.
